Life insurance premiums an S corporation pays on an officer are deductible on Form 1120-S only when two conditions are both met: the corporation is not a direct or indirect beneficiary of the policy, and the premium qualifies as reasonable compensation for the officer’s services. If the corporation stands to collect the death benefit, whether outright or to fund something like a buy-sell agreement, the premium is not deductible at all.
When the Premium Is Deductible
The deduction rides on Section 162, the same rule that lets a business deduct reasonable compensation for services.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses For a life insurance premium to qualify, the officer’s family or estate must be the named beneficiary, and the corporation must receive no financial benefit from the policy. Two common structures work.
The first is group term life insurance. The corporation deducts the full premium as a compensation expense. For a rank-and-file employee, the first $50,000 of coverage is tax-free, and any coverage above that produces imputed income using the IRS Premium Table based on the employee’s age.2Office of the Law Revision Counsel. 26 U.S. Code 79 – Group-Term Life Insurance Purchased for Employees The imputed amount is added to W-2 wages, and the corporation keeps the full deduction either way.3Internal Revenue Service. Group-Term Life Insurance
The second is an individual policy paid by the corporation with the officer’s family or estate named as beneficiary. There is no $50,000 exclusion in this arrangement. The full premium is taxable income to the officer, reported on the W-2, and the corporation deducts the full amount as compensation, subject to the same reasonableness standard that applies to salary.
When the Premium Is Not Deductible
Federal tax law flatly prohibits deducting premiums on any life insurance policy where the taxpayer is directly or indirectly the beneficiary.4Office of the Law Revision Counsel. 26 U.S. Code 264 – Certain Amounts Paid in Connection With Insurance Contracts Key person insurance is the textbook example. The corporation insures an officer to protect itself against the financial loss of that officer’s death, so the corporation collects the death benefit. The premium is not deductible even though it would otherwise look like an ordinary business expense.
The rule reaches further than policies naming the corporation outright. If the proceeds are earmarked for a corporate obligation, such as funding a buy-sell agreement to purchase a deceased shareholder’s stock, the corporation is treated as an indirect beneficiary and the same non-deductibility applies.5eCFR. 26 CFR 1.264-1 – Premiums on Life Insurance Taken Out in a Trade or Business
The reasoning is symmetric. Death benefit proceeds a corporation receives are generally excluded from gross income.6Office of the Law Revision Counsel. 26 USC 101 – Certain Death Benefits The code does not allow a deduction for expenses that generate tax-free income.
The 2% Shareholder Rule
Most officers of an S corporation own well more than 2% of the stock, and that changes the analysis. When an officer owns more than 2% of the corporation’s stock on any day during the tax year, federal tax law treats them as a partner rather than an employee for fringe benefit purposes.7Office of the Law Revision Counsel. 26 USC 1372 – Partnership Rules to Apply for Fringe Benefit Purposes The ownership test includes stock attributed through family members and related entities.
The consequence for group term life insurance is that the $50,000 exclusion disappears for a 2% shareholder-employee. The entire premium paid on that officer’s behalf is taxable income, reportable in boxes 1, 3, and 5 of the W-2. The corporation still gets the deduction; the officer just loses the tax-free treatment ordinary employees receive.
The Form 1120-S instructions carry this through to the return itself. Fringe benefit expenditures for officers and employees owning more than 2% of the stock go on Line 7 (Compensation of officers) and are reported as W-2 wages.8Internal Revenue Service. Instructions for Form 1120-S (2025) For officers at or below 2%, the same benefits belong on Line 18 (Employee benefit programs). Getting the line wrong either understates the officer’s taxable compensation or misreports the corporation’s deductions.
Reporting on Form 1120-S
Where the premium lands on the return depends on who benefits from the policy.
Deductible Premiums Treated as Compensation
Premiums that qualify as officer compensation are included in the total on Line 7 (Compensation of officers).9Internal Revenue Service. Form 1120-S – U.S. Income Tax Return for an S Corporation If the corporation’s total receipts reach $500,000 or more, it must also complete Form 1125-E to break down officer compensation.8Internal Revenue Service. Instructions for Form 1120-S (2025) Premiums for non-officer employees go on Line 8 (Salaries and wages) instead.
Non-Deductible Key Person Premiums
Non-deductible premiums do not appear on any deduction line. They create a book-to-tax difference reconciled on Schedule M-1, where the non-deductible amount is added back to book income. The expense also flows to Schedule K, Line 16c, and passes through to each shareholder on Schedule K-1, Box 16, using Code C.10Internal Revenue Service. Instructions for Form 1120-S
Basis Effects for Shareholders
Life insurance creates basis adjustments on both sides of the ledger, and shareholders who ignore them will eventually misreport gain on a stock sale or the taxability of a distribution.
Non-deductible key person premiums reduce each shareholder’s stock basis. The statute decreases basis for any corporate expense that is neither deductible on the return nor chargeable to a capital account.11Office of the Law Revision Counsel. 26 USC 1367 – Adjustments to Basis of Stock of Shareholders That reduction happens even though the corporation gets no tax benefit from paying the premium. It stops shareholders from claiming higher basis later when they sell stock or take distributions.
When the corporation eventually collects the tax-free death benefit, the proceeds increase each shareholder’s stock basis through the separately stated income items on Schedule K-1.11Office of the Law Revision Counsel. 26 USC 1367 – Adjustments to Basis of Stock of Shareholders Basis goes down when premiums are paid and up when the benefit comes in.
Deductible premiums treated as compensation work differently. They reduce the corporation’s ordinary business income, which reduces the income flowing through on Schedule K-1. No separate basis adjustment is needed because the reduction already ran through the income figure that drives basis.
A shareholder who skips the basis reduction from non-deductible premiums for several years ends up with an inflated basis on the books, and the error surfaces as underreported gain on a future stock sale or an unexpectedly taxable distribution.
